A few decades ago, flying was still a rare luxury, but today it is a natural part of many of our lives.

However, growing air traffic is not only putting a strain on airports, but also on our planet. This is why it has become a key issue to find ways to make aviation greener, more economical, and safer at the same time—even in the harshest weather conditions. Hungarian researchers are working on this side by side with the world's largest aircraft manufacturers.
